An apk runs just fine in my device. App internally makes a web service call in an async task to a server to fetch data. But when I upload same apk to google's cloud test lab and run Robo test for it,same web service call fails with error as:
Caused by: java.lang.RuntimeException: Failed : HTTP error code : 400
Does google's cloud test lab don't support such calls or Robo tests have some limitations?
